The rifle shown in FIGURE 1 includes a stock 10,

barrel ll, receiver 12 and recoil block 13. The barrel 11 is threaded in the receiver barrel ring 14, and the recoil block 13 is secured to the stock by means of a screw A feature of the invention is the breech bolt sleeve 16 shown in FIGURES 1, 2, 7 and 8, and which sleeve is comprised of a body 17 having a longitudinal bore 18 therethrough for slidably and rotatably receiving the breech bolt 19. One side of the sleeve 16 has a laterally projecting shoulder 20 for sliding action in a longitudinal groove 21 in the inner side surface of the receiver 12 and the recoil block 13. As shown in FIGURE 1, the rearward end of the longitudinal groove 21 is transversely milled or otherwise transversely formed to provide a stop 22 to limit the rearward movement of the sleeve 16. The lower surface of the sleeve body 17 is channeled, as at 23, to receive the forwardend of the finger lever 24, where the latter is hingedly connected therein by means of a transverse hinge pin 25. As shown in FIGURES 7 and 8, the breech bolt 19, which is in axial alignment with the barrel -11, includes a firing pin 26 therethrough, and which pin includes a head 27 on its rear end, and firing pin spring, not shown. Parallel with the firing pin 26 and also slidably extending through the breech bolt 19, there is an ejector pin 28 which also has a head 29 on its rearapparent from the following description and accom- I ward end, and which head is positioned to engage a stop 30 in the upper portion of the recoil block '13 when the sleeve 16 approaches the stop 22 in the groove 21'. As

shown in FIGURES =1 and 7, the upper rear portion of Y the sleeve 16 is cut away to accommodate the firing pin head 27 and the ejector pin head 29. Also shown in these figures is the ejector pin spring 31 for normally maintaining the ejector pin 28 inside of but flush with the forward end of the breech bolt 19.

The breech bolt19 has locking lugs 32 for engaging projections 33in and integral with the receiver .12.. As shown in FIGURE 9, the projections 33 are arranged to receive and pass the locking lugs 32 when the latter are vertically positioned. When the lugs 32 are forwardly of the projections 33 the bolt 19 is rotated approximately 45 degrees so as to'provide for locking of said bolt. Such partial rotation may be carried out by means of the arrangement and construction shown in FIGURES 5 and 7 wherein the surface of the bolt is provided with spaced and correspondingly disposed spiraled slots for coaction with the inner ends of headed pins 35 in a longitudinally disposed actuating slide 36. As shown in FIGURE 7, the slide 36 is mounted in an elongated slot 37 in one side of the sleeve 16 and above the projecting shoulder 20. An upwardly and rearwardly directed finger 38 integral with the lever 24 imparts a cam action to the pins 35 causing forward and rearward movement of the same, the direction of which depends upon the movement of the lever 24, and which pins, in turn, impart a cam action to the bolt 19 by way of the slots 34,

The upper forward portion of the sleeve 16 includes a forwardly projecting cartridge head support 39 which is notched, as at 40, to accommodate the upper breech bolt lug 32. Beneath the cartridge head support 39, and in the lower forward portion of the body 17, there is a slot 41 to accommodate a hinged extractor 42, the latter being shown in FIGURE 1 where the same is hingedly supported in the sleeve body 17 by means of a transverse pin 43. The claw of the extractor is normally urged toward the rim of the cartridge 45 by means of a compression spring 46 mounted in and projecting from the sleeve body 17.

The modified form of breech bolt 44 illustrated in FIGURE 6 includes the previously locking lugs 32a, firing pin 26a, and their component parts, but differ in its means for partially rotating and longitudinally moving the bolt. Instead of the cam slots 34, this form of the invention includes a pair of spaced spiraled teeth 45a on the rear end of the bolt providing a spiraled groove 45' therebetween, and which teeth are actuated by a forwardly directed finger 46a integral with the finger lever 24. It is believed to be obvious as to how the body 17 of the sleeve 16 would be modified to accommodate the teeth 45a and finger 46a.

The finger lever 24 heretofore described as being hingedly connected at its forward end with the sleeve 16, extends downwardly through an opening 47 in a magazine channel 48 where the lever is provided with the usual trigger guard 49 and finger lever loop 56. A link 51 is hingedly connected at one end with the finger lever 24 by means of a pin 52 whereas the other end of the link is hingedly connected in a slot 53 in a forwardly directed shoulder 54 in the lower forward portion of the recoil lock 13 and secured for hinged slidable movement therein by means of a transverse pin 55. The pin 55 is limited against displacement by means of vertical stops 56 brazed to the magazine channel 48 at the rear end of the opening 47. When the action is in its closed position, the link 51 assumes an acute angle with respect to the axis of the barrel 11.

The finger lever 24 is relatively wide where the same traverses the magazine channel 48 when the action is in its closed position so as to accommodate the hammer 57 which is hinged to the lower forward portion of the lever by means of a transverse pin 58. The hammer 57 extends upwardly from the pin 58 to a position where the same may strike the head 27 of the firing pin 26 and thence extends rearwardly, downwardly, and again forwardly where the same terminates in a forwardly and upwardly hook 59. Th hook 59 is designed to engage a flat surface 60 forming a rear part of an elongated flat plunger 61 slidably mounted on the link 51. The forward end of the plunger 61 includes an elongated opening 61a around the link hinge pin 52, and which plunger includes a longitudinal plunger 61b therein for hearing against the hinge pin and which longitudinal plunger is spring loaded by means of a spring, not numbered, for normally urging the plunger 61b toward the hinged pin 52 extending to the rear end of said link The fiat parallel surface 60 of the plunger 61 has a laterally projecting cam 62, the purpose of which will be explained in the description of operation to follow. The finger lever 24 is offset and channeled to accommodate the hinged end of the hammer 57 as well as other parts hereinafter described, and which channeled offset is indicated by the reference numeral 63.

The trigger 64 also mounted in the lever 24 by means of a pin 65, which trigger is of thin construction and of flexible material in order that the trigger may yield when the action thereof is blocked in the manner to be described. Inside of the trigger guard 49, integral with the trigger 64, and forwardly of the trigger pin 65, there is an integral shoulder 66 having a trigger spring 67 thereunder. Also integral with the trigger there is an upwardly projecting trigger sear 63 having a rearwardly directed hook 69 on the upper rear end thereof for engaging a hook 70 on the end of a depending spring loaded hinged hammer sear 71. The hammer sear 71 is hingedly mounted on the rear of the hammer 57 by means of a pin 72. i

A feature of the invention has to do with asafety arm 73 hingedly mounted in the finger lever 24 above the trigger guard 49, forwardly of the trigger sear 6S, and arranged for coaction with the latter. The safety arm 73 includes a transverse pin 74 forwardly of a rear and upwardly directed projection 75, the latter being for coaction with the forward curved surface of a trigger sear 68. The curve 76' is in anare about the safety arm pivot pin 74, and the rear surface of the projection 75 is also generated about the same point. When the rear portion of the arm 73 is down, the forward upper end of the sear 68 is in contact with the safety arm projection 75. The safety arm 73 includes a depending stop 77 for contact with the top of the finger guard' 49, but this end of the safety arm is normally urged upwardly by means of a spring 78. The forward end of the safety arm 73 extends forwardly of the pin 74' where it has a depending projection 79 for coaction with a conventional safety button 80. As will become apparent, the safety arm 73 will operate in conjunction with or independently of the conventional safety button referred to.

The main spring assembly 31 includes a sleeve 82, a telescoping plunger '83 therein, a shouldered fitting 84 pivotally connected to the hammer 57 by means of' pin $5, a shouldered pointed bearing 86- on the end of the sleeve and a compression spring 88 between the latter and the hinged fitting 84. The pointed bearing 86 engages a notch 87 in a hinged main spring abutment arm 89 which is pivotally connected at. one end thereof to the safety arm hinged pin 74. The rear upper edge of the hinged abutment 89 is in contact with the forward edge of the safety arm projection 75, and the upper forward end of the abutment has a cam 90 thereon for coaction with the cam '62 on the plunger 61, and which has to do with releasing the safety just before the action is completely closed. A transverse pin 91 in the finger lever and its oifset 63 provides a stop for the hammer 57'.

The scissors type lift 92, shown in FIGURE 11 is comprised of a horizontal follower 93 for supporting cartridges 45 thereon and crossed forward and rear arms 94 and 95 which are pivoted to each other at their intersection by means of a pin 96. A slotted guide 97 is secured to the forward lower surface of the follower 98 where it receives a pin 98 extending through the forward end of the rear arm 95. The rear endof the rear arm 95 has an elongated notch 99 for hingedly engaging the link pin 55 in the recoil block 13. The forward end of the arm 94 is forwardly and upwardly inclined where it pivotally engages a transverse pin 100 through the magazine channel. As shown in FIGURES l and 11, this arm 94 extends through an opening 101 in the forward magazine wall 102. A coil spring 103 engages the arm 94 and is mounted around the pin 10!), which spring is additionally secured to a stationary part, not shown, of the rifle. The spring 103 is arranged to normally raise the follower 93 and the cartridges 45 supported thereon. The rear arm 95 has a laterally projectingbutton 104, the shank of which extends through avertical slot 105 in the side wall of the magazine channel 48.

As shown in FIGURES 8 and 10, a magazine 106 is located in one side of the magazine channel 43 and includes an inner vertical longitudinal wall 107 which extends upwardly into the receiver 12 where it terminates to provide passage means for the upper cartridge moving from the magazine into the receiver.

In FIGURE 1 the rifle is shown in its closed cocked position and ready to fire. Actuation of the trigger 64 releases the trigger sear 68 from the hammer sear 70, and the hammer 57 strikes the firing pin head 27 which, in turn, causes the firing pin 26 to fire the cartridge 45. The finger lever 24 is then moved downwardly by means of the finger lever loop 50, and at which time the action of the finger 38 or 64:: on the lever causes the breech bolt to rotate and unlock the lugs 32 from the projections 33 in the receiver 12. Continued downward movement of the lever 24 withdraws the fired case from the barrel 11 by means of the extractor 42 as the sleeve 16 is moved rearwardly. Even before the lugs 32 are rotated there is enough delayed action between the lever and the bolt to disengage the cam 94 on the hinged abutment 89 from the cam 62 on the plunger 61 and cause the abutment to depress the safety arm 73 and cause the projection 75 on the latter to engage the trigger sear 6%. Continued downward movement of the lever 24 causes the hammer hook 59 to pass the end of the plunger 61. It is to be understood that during this opening operation the main spring assembly 81 maintains the hinged abutment 89 against the projection 75 on the safety arm 73, and as the finger lever 24 reaches its completely open position the ejector pin head 29 contacts the stop 30 in the recoil block 13 and causes the ejector pin 28 to disengage the cartridge case 45 from the extractor 42 and eject the case downwardly through the slot 1M in the magazine channel 48.

As the finger lever is closed, a cartridge 45 from the magazine tee is picked up in the usual manner and the chambering operation begins. At the same time the hammer hook 59 approaches and engages the flat longitudinal surface ea on the plunger 61. During the lever closing operation, the main spring assembly 81 is acting on the hinged abutment 89 which, in turn, maintains the projection 75 on the safety arm '73 again-st the forward edge of the trigger sear hook 69 to engage the hammer sear 71, and further continued closing action of the lever disengages the hammer hook 59 from the plungers flat surface 69. Final closing of the finger lever 24 causes the cam 99 on the hinged abutment $9 to engage the cam 62. on the plunger 61 and thereby release the hinged abutment from the projection 75 on the safety arm which, in turn, moves upwardly by action of spring 78, provided there is no pressure on the trigger 64.

Prior to final closing of the trigger lever 24 the cartridge 45 is completely chambered and the breech bolt 44 is locked by rotation of the lugs 32 integral therewith by action of the finger 38 or 46a on the spiraled slots 34 or spiraled teeth 45a. It is pointed out that the conventional button safety 84 does not interfere with the action of the safety arm 73, and that if the conventional safety is on the same will hold the safety arm projection against the trigger sear 68 in the intended manner.

The invention is not limited to the exemplary construction herein shown and described, but may be made in various ways within the scope of the appended claims.
